Coffee-pot.

To all whom t may concern.'

Be it known that I, FREDERICK ELLIOTT BOARDMAN, a citizen of theLUnitedStates, and resident of the borough of Brooklyn, Ycounty of Kings,city and State of New York, have invented certain new and usefulImprovements in Coifee-Pots, of which the Y following is a speciication.

. .The invention relates to a coffee ipot constructed v1n a manner lsoas to have certain novel and important features. The novel -features arenot-merely decorative effects, as

f is often the casewith devices aswell knownv as coffee pots, butin'this-instancethey have to do with the'production Vof a pot `or urnthat maybe used in an ordinary manner and yet one from which will beabsent certain objectionable features.

I have found-.that in ,using an, ordinary coffee pot, it has been for along time customary toI place in thel pota quantity of ground orpulverized coffee together with' a desirable amount of cold water. Thepot heating device where the heat is applied.v As the water heats itexpands and when the boiling point of the water has been reached, thecoffee boils with the water. The boiling of water containing coffee isaccompanied by violent ebullition with the result that unless closelywatched the coffee or the contents of the pot will boil over on tothestove or heating device, and not only will the contents be lost, butthe heating device will be soiled or made unsightly.

The boiling over of a coiee pot or urn is a serious matter particularlyif gas is used as the heating means. Not only is the average gas stoveso constructed that it cannot without difficulty be cleaned but ytheboiling over of the coffee may extinguish the gas flame allowingunburned gas to escape.

My invention then has to do with the construction of a coffee pot, thecontents of which cannot boil out of the pot. The construction andoperation will be set'forth as thespecification progresses.- Y

The following is what I consider a good means of carrying out thisinvention and,

The accompanyng drawings should be referred to for a completeunderstanding of the specification which follows The drawing shows in asingle figure a central vertical section.

I khave called attention to the fact :that

this yinvention relates to coifee pots vandtI now desire to set forththat. my pot isuse'd ,inthemanner that ordinary coifee pots are used. f

My device consists of an interior cylindrical member indicatedv at 1, of,aY Size as shall be desired and sufliciently largey to receive adesirable amount of-liquid.`

,Y This cylindrical `memberamay be made ofjblock tin, or iron,rnickelplated orenameled, or. of anyother suitable material,

kand -I prefer that it yshould bein theshape of an extended cylinder. lI. -a Surrounding the cylinder l is a larger andshorter cylinder2 madeoffs'imilar material ,as cylinder l andattached theretoby soldering orotherwise at a point above the lower end of the cylinder 1 *but belowthe mid height of Vthat cylinder'. -The usual point lofY attachmentisindicated at 3. f

rlhe inner cylinder has its lower end closed and the outer cylinder isalso provided'with a bottom in the form of a ring 4.

In the upper open end of the outer cylin l der, I may arrange `a cover5, and Vtovone side of this cylinder a handle 6 is secured. Thesemembers perform ordinary functions that will be understood from theirtitles.

Entering theouter cylinder and at a point Y opposite the handle 6 is aspout 7, arranged at an angle and continuing inward andv opening intoythe inner cylinder 1. Although the outer portion of the spout is solidand tion of this member, that portion which is between the inner andouter cylinders is provided with a plurality of perforations asindicated at 8, and I also provide perforations 9 through the wall oflthe cylinder 1 and by means of which liquid may passj from the innercylinder into the spout 7.

In operating my device a quantity of suitably prepared codee and coldwater are placed in the inner cylinder, the water being brought up tothe line 10 or above or below this line as requirements may dictate.

My device is. next subjected to heat, the heat being applied to thelower portion '11 of the inner cylinder.

The coffee is allowed to reach the boiling point and if boiling takesplace, kthe coffee and liquid will pass upward out of the in-y nercylinder into the space 12 between the inner and outer cylinders, and Ihave found that a long and extended application of heat will not causethe cotiee or the liquid contained in my coti'ee pot to boil out of thepot. This is important as it develops the principle that I have laboredto accomplish, the production of a coffee pot that may be saielyoperated without requiring jconstant attention.

It is obvious that sizes and proportions may be changed at will and thatmy device may be made more or less decorative as desir-ed, and thatother modifications may be made Within the scope of the appended claimswithoutdeparting from the principle or sacrificingrthe advantages of theinvention.

Having carefullyand fully described my invention, what l claim anddesire to secure by Letters Patent is:

l. A coffee pot comprising a plurality of cylindrical members one withinthe other and an angularly disposed spout secured `to the innercylindrical member and projecting through the outer cylindrical member,said spout being perforated between `the said cylindrical members asherein specified.

2. A vcoffee pot comprising a cylindrical member a. smaller cylindricalmember witbin said first cylindrical member and projecting therefrom andproviding a chamber between said cylindrical members, a spout pasS- -ingthrough the wall of the larger cylindrical member and connecting withthe wall of the smaller cylindrical member, the said spout beingprovided with a plurality of perfor-'ations in that portion whichextends between the walls of said cylindrical members.

3. A coffee pot comprising an inner cylinder, an outer cylinder oflarger diameter Vand secured to said inner cylinder at a point above thelower end thereof, a disk closing the lower end of said outer cylinderand surrounding said inner cylinder and a spout secured to the innercylinder and projecting through said outer cylinder, said spout beingYperforated between the said cylinders as herein specified.
